SEPS the Slovak transmission grid operator, integrates the country’s transmission network with Europe’s leading electricity transmission networks. SEPS has implemented TIM for day-ahead and intraday forecasting of active power losses, so called “technical losses”. This allows a more accurate prediction of electricity required to cover transmission losses. Better predictions result and better timed market nominations which ultimately leads to reducing costs. TIM has been seamlessly integrated into the system landscape of SEPS as a module of the Energy Management Execution System and requires little maintenance or involvement of machine learning experts.
